In addition to making groundbreaking nude and BDSM photographs, Jacques (and Charles) Biederer is among the very first to create erotic S&M stag reels in the 1930s. The total number of films may never be known, but at least three, possibly more, have survived to the present day.
A vast collection of pornographic and fetish reels made in France from the 1920s to the ’60s have been preserved by Editions Astarte’s Les Archives d’ Eros series. In 2000, Cult Epics (the company that released Irving Klaw’s 1950s bondage films on disc) made these obscure films availabe on DVD in a five-part Vintage Erotica series. The second volume, Vintage Erotica anno 1930, has two extraordinary 3-minute F/F shorts marked “Editions Ostra” on the title cards. A third film, La Vase Brise, appears in Vintage Erotica anno 1940.
Biederer used the same sets, models, props — even the same whips — seen in his many photographs. He also shot still photos of the movie sessions just as Irving Klaw would do twenty years later in New York.
Dressage au Fouet (Raising with the Whip) begins with a topless submissive wearing stockings, shoes, and panties, kneeling before her lingerie-clad mistress. Her wrists bound with rope, she is lashed with a long whip as she kisses the feet and legs of her mistress. Next, the sub is whipped about 30 times while standing then lays across a table. With her undergarment pulled down she is whipped again. The last shot is a close-up of the mistress kissing her slave.
The second film-loop, Sous Les Caresses du Martinet (Under the Caresses of the Martinet) has a more playful, consensual tone. A woman wearing only panties, stockings, and shoes stands before a mirror lightly flogging herself with a martinet. She then flails away at a female submissive who is sitting in a chair. The submissive girl, who seems to be enjoying herself, is flogged in a variety of positions. (See first photo in gallery below. To watch the film, see the Links section.)
It is not known if Biederer directed these himself. Both featurettes are reasonably well-edited and contain a surprising number of close-up “reaction” shots, something few fetish filmmakers, including Klaw, bothered to include.
The third film, La Vase Brise (The Broken Vase), is a simple two-minute vignette about a clumsy maid who knocks over a vase while dusting. Her mistress has her kneel on a chair where she gets a brisk hand spanking.
